EGG-TESTER.

Application filed Becember 20, 1907.

11S invention relates to heating attach ments for lamps and has for its object to provide a conniaratively simple and inexpensive device of this character which may be used as a heating or cooking device and also for testing or candling eggs.

A further object of the invention is to pro vide a lamp attachment including a casing adapted to surround the burner of a lamp and having its upper end llared laterally to form a support for the receptacle containing the food to cooked, there being an opening formed in one side of the casing in alinement ith the flame of the lamp bur or to permit the d vice to be employed for testing or candling eggs.

A further object is to provide a testing tube or hood adpted to detachably engage the adjacent "wall of the casing at the opening therein and designed to support the eggs during the testing operation, said hood being provided ith attaching arms which embrace the casing and are provided with interlocking terminals.

still further object of the invention is to provide a heatin attachment that may be used as a chimney for night lamps and also as a vapor inhaler for sick rooms.

Further objects and advantages will appear in the following description, it being understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claims.

In the accompanying drawings forming a part of this specification: Figure 1 is a side elevation partly in section of a lamp attachment constructed in accordance with my in* vcntion. Fig. 2 is a front elevation of that portion of the casing having the display opening formed therein and showing the manner of securing the mica strip in position on the casing. Fig. 3 is a perspective view of the testing tube or hood detached.

Similar numerals of reference indicate corresponding parts in all of the figures of the drau in gs.

The improved attachment forming the subject matter of the present invention may Specification 01 Letters Patent.

be used in connection with a lamp, gas burner or similar heating medium. and by ray of illustration is shown in position on a amp of the ordinary construction in which 6 designates the body portion and 7 the burner.

The device consists of a cylindrical casing 8 having tapering side walls the upper ends of which are extended laterally at 9 and thence bent upwardly to form an annular flange 10 adapted to receive and support a receptacle containing the food to be cooked, there being a plurality of ports or openings 11 formed in the side walls of the casing immediately below the oil set portion thereof to permit the escape of the products of combustion from the lamp.

The casing 8 is provided with a relatively large opening 12 preferably circular in shape and disposed in alinernent with the flame from the lamp burner, said opening being normally closed by a strip of mica, glass or other transparent material 13. The mica is disposed in contact with the interior walls of the casing by means of a frame 14 having an opening formed therein for registration With the opening in the casing 8. The frame 1 1- is preferably curved to conform to the curvature of the interior walls of the casing and is locked in engagement with the mica strip 13 by clips or similar fastenin devices 15, which latter are riveted or otherwise rigidly secured to the interior Walls of the casing, as shown.

Associated with the casing is a hood or testing tube 16 which bears against the exterior Walls of the casing at the opening 12 and is provided with resilient arms 17 which encircle the walls of the casing and serve to rotain the hood in position on the latter. One longitudinal edge of each attaching arm 17 is formed with spaced notches 18 which engage the walls of the notches of the mating arm and thus serve to lock the arms in engagement with said casing.

The upper and lower portion of the hood 16 is preferably curved or rounded at 19 to conform to the shape of the exterior Walls of the casing thereby to prevent the escape of the rays of light from the burner and direct said light through the hood. The lower edge of the casing is preferably formed with a marginal row of draft openings 20 so as to permit free circulation of air through the casing.

When the device is used for cooking food,

heating or boiling water or for similar purposes the receptacle containing the food or water is placed on the flange 10 and in which position the heat from the burner will thorou hly cook the food.

in using the device for testing or candling eggs said eggs are held against the outer end of the tube or hood 16 with the large end thereof inserted within the tube and in which position the rays of light from the burner i will internally illuminate the eggs and render their condition readily visible.

When the testing tube or hood is not in use the same may be readily detached by disengaging the locking notches 18 and expanding the arms laterally as will be readily understood. The attachment may also be used as a chimney for night lamps and as a vapor inhaler for sick rooms, the vapor forming fluid being placed in a suitable receptacle and supported on the flange, in the manner before stated.

The heating devices may be made in differ ent sizes and shapes and if desired the casing may be formed with one or more openings so that a plurality of testing tubes or hoods may be employed.

From the foregoing description it will be seen that there is provided an extremely simple, inexpensive and ellicient device admirably adapted for the attainment of the ends in view.

Having thus described the invention what is claimed is:

1. A device of the class described comprising a casing having an opening formed there in, and a tube detachably secured to the easing at said opening and provided with resilient attaching arms having interlocking ter minals.

2. A device of the class described comprising a tapered casing having an opening formed therein, a tube detachably secured to the exterior walls of the casing at said open,

ing and surrounding the latter, and resilient attaching arms extending from the tube and having their terminals embracing the casing and provided with interlocking parts.

3. A device of the class described comprising a tapered casing having an opening formed therein, a tube detachably secured to the casing and having its inner end inclined to conform to and adapted to bear against the tapered walls of the casing at said opening, and resilient attaching arms formed integral with the tube and arranged to frictionally engage the tapered walls of the casing, the upper longitudinal edge of one of the attaching arms and the lower longitudinal edge of the other attaching arm being formed with locking notches adapted to interengage for detachably securing the tube in position on the casing.

In testimony that I claim the foregoing as my own, I have hereto ailixed my signature in the presence of two witnesses.
